SEWING-MACHINE RUFFLER.

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed February 8, 1919. Serial No. 275,832.

To all whom it may concern:

Be it known that I, Hnnennr H. RUSSELL, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented or discovered certain new and useful Improvements in Sewing-Maehine Rufllers, of which the followin is a specification, reference being had t erein to the accompanying drawing.

This invention relates to that class of sewing machine ruffiers in whichv the ruffling blade is operated from the needle bar of a sewing machine. The present invention has for its object to lessen the cost of manufacture by providing novel means, which may be produced at little expense, for regulating the stroke of the rutl'lin blade. In this class of rufllers as recently generally constructed a regulating screw has been provided for regulating the stroke of the rullling blade by taking up more or less lost motion, such regulating screw being mounted in a threaded ear or part. See, for example, U. S. Patents NOS. 1,041,730, 1,044,645, and 1,261,628. In the present improved construction the regulating device consists of a plate having an opening of varying width and into which opening a projection on the ,pendulous lever extends, said regulating plate being pivotally mounted so that it may be adjusted to different lateral positions to bring parts of the said opening of different widths into register with the said projection on the pendulous lever, means being provided for retaining the said regulating plate in different positions of adjustment.

In the accompanying drawings Figure l is a side view of the improved rufiler, and Fig. 2 is a plan view thereof. Fig. 3 is a bottom View of the regulating plate, and Fig. 4 a detail view of the retaining pawl therefor.

. Referring to the drawing, 12 denotes the frame of the rufller comprising a presser foot part 13 adapted to be attached to the presser bar of the sewing machine. Pivotally mounted on the upright side portion .of the frame is a pendulous lever 14 the lower end of which is jointed to a sliding part 15 earryingthe ruffling blade 16 which cooperates with the usual separator plate 17 fixed to the frame part 12 of the rullier. The operating lever 18 is pivotally mounted on the frame part of the rufller coincidentally with the pendulous lever 14 and is forked at its forward end for engagement with a pin or roller stud on the needle bar of the machine. The parts thus far described are of the usual construction and operate in the usual manner.

In the present improved construction the pendulous lever 14 is provided with an upwardly projecting part or short arm 19 which extends into an opening 20 formed in a regulating plate 21, said regulating plate being pivotally attached, by means of a pin orscrew 22, to a laterally extending lug or car 23 formed on the operating lever 18. The opening 20 is tapered or, in other words, is of varying widths at its different lateral parts between the side walls of said opening and which side walls contact with or engage opposite sides of the said arm 19 to ope ate the pendulous lever 14 with which the milling blade 16 is connected. The pivotal mounting of the regulating plate enables the same to be adjusted to different lateral positions to bring different parts of the opening 20 into register with the short arm or projection 19 on the pendulous lever 14 so that there will be more or less lost motion between the operating lever 18, having a constant movement, and the said pendulous lever from which latter the ruffling blade is operated.

Attached to the car 23 on the operating lever 18 is a spring pawl or retaining plate 24 having a teeth 25 adapted to engage an indented or roughened portion 21 on the under side of the regulating late 21 in order to retain said plate in (li 'erent positions of adjustment.

Owing to the fact that the regulating plate 21 and the parts cooperating therewith may be stamped out of sheet metal the improved construction enables rufliers embodying the present improvement to be manufactured more cheaply than similar rufflcrs heretofore in use in which the means for regulating the strokes of the ruflling blades required screws and tapped parts entered thereby.

Having thus described my invention I claim and desire to secure by Letters Patent:

1. In a sewing machine rufller, the combination with an operating lover, of a pendulous lever having a short arm or projection, a ruflling blade operated from said pendulous lever, an adjustable regulating plate mounted on said operating lever and having n openi g enter d bysaicl rmw melee.

tion, said opening havingvarying idths at its different parts, and means for retaining said regulating plate in different posi: tions of adjustment.

I In a sewing machinerL1 er-,1the00min? nation with an operating lever provided with a laterally extending lug or ear, of a pendulous lever having a, short arm or .projection, arufiling blade operated from said pendulous lever, an adjustable regulating plate pivotally mounted on said lug or ear and having an opening entered by said arm or projection, said opening having varying w dths at its different parts, and means for retaining said regulatlng plate in different positions of adjustment.

3.,111 a sewing machine ruflier, the combination with an operating lever, of a pendule ma lous lever having a short arm or projection, a ruflllng; blade operated' from sald penduv lQus: lever, an adjustable regulating plate mounted on said operating lever and having an opening entered by said arm or projection, said opening having varying widths at in the presence of two witnesses.
